Donor-advised funds.

Instead of making a gift to a single charity, some might perfer to make a gift that supports multiple charities.  The mechanism for doing so is called a donor-advised fund, which is basically a simplified version of a private foundation.  First, you establish a donor-advised fund that invests your donations as aggressively or conservatively as you wish.  You can then suggest qualified charities to receive distributions from the account.  Your donation to the fund is tax-deductible.
